Chief prosecutors from the Western Balkans met in Sarajevo for the third consultative forum focused on joint investigation teams (JITs). The meeting also resulted in the launch of a new practical guide for practitioners across the region. According to the Eurojust announcement, the forum was held in the framework of cooperation among Western Balkan prosecutors, with a specific emphasis on how joint investigation teams can support cross-border investigations. The guide released at the Sarajevo meeting is described as a practical handbook for practitioners. Eurojust says it is designed to help those involved in investigations apply and work with JITs in practice. The event is framed as part of ongoing work to strengthen the operational use of JITs among Western Balkan legal practitioners. By convening prosecutors and issuing updated practical guidance, the forum aims to provide clearer working support for teams carrying out investigations together. No arrests, prosecutions, or case outcomes are described in the source information.
